    I think not knowing the state of a coin flip is a little different from Schrödinger's paradox. I'll try to explain it.

    The concept of a coin flip serves as an excellent analogy to illustrate the differences between classical and quantum mechanics. In the macroscopic world, a coin's state is determined upon flipping, regardless of observation. However, in the quantum realm, observation itself plays a crucial role in determining the state of a particle.

    In classical physics, exemplified by a traditional coin toss, the outcome is determined as soon as the coin lands, even if no one observes it. The coin will always have a heads side and a tails side, and its state is fixed upon landing, irrespective of whether someone looks at it or not. Our lack of knowledge about the outcome does not affect the coin's actual state.

    Quantum mechanics, however, introduces a fundamentally different perspective. In the quantum world, particles can exist in a superposition of states until they are observed or measured. A hypothetical "quantum coin" would not have a definite state until interaction occurs. This is not merely a lack of information but a fundamental property of quantum systems.

    The famous Schrödinger's cat thought experiment illustrates this concept on a macroscopic scale. In this scenario, a cat is placed in a sealed box with a radioactive source and a poison that will be released when the source decays. According to quantum mechanics, until the box is opened, the cat is theoretically in a superposition of states - both alive and dead simultaneously.

    However, this apparent paradox can be resolved through the principles of quantum decoherence and the Copenhagen interpretation. Decoherence explains how quantum superpositions break down when a quantum system interacts with its environment. In the case of Schrödinger's cat, the cat, being a macroscopic object, constantly interacts with its environment inside the box. These interactions cause rapid decoherence, collapsing the quantum superposition into a definite state (either alive or dead) long before the box is opened.

    This resolution bridges the gap between quantum mechanics and our classical understanding of reality. It demonstrates that while quantum effects are prevalent at the microscopic level, they typically don't persist in large-scale systems due to constant environmental interactions. The act of observation doesn't determine the cat's fate; rather, it reveals the already-determined state resulting from decoherence.

    First of all, do not panic. Even if Trump won, it doesn't mean that the country is doomed and will fall apart in a couple of months. After all, it took 20 years for Putin to became a tyrant, and he was starting with circumstances in favor of him. The decision to relocate will impact your life much more than decision to stay, so you need to think about it carefully and rational. And if you finally decided, you have to take full responsibility for it.

    If you still want to do it after all emotions are settled down, try to travel to a neighbouring country and live there for a month or two. In that way you could learn what unique challenges you will face as an immigrant. If you will find that all the issues are manageable and you actually feel better outside of USA then try to list everything that is most important to you in the future place of living. With that list it will be much more easier to reduce the scope for searching. Also it will help if you could travel to the final candidate countries and see for yourself if it will suit you.

    Edit: I just realised that I assumed you are from USA, despite you didn't mention it in the post. I'm sorry if I'm wrong. Anyway I still think that this advise will help anyone from anywhere with first steps of moving.

    In my experience a lot of people perceive information better with visual images. If you want to describe abstract things, it is better to make them more concrete and describe through simplified models and analogies. But be aware that abstraction and details should not be hidden, but rather clearly distinguished from simplified models.

    If you want to describe the sequence of steps of the algorithm, nothing works better than the sequence diagram.

    If you want to show the change of state, then the flow chart will do the job. Also you might find useful activity diagram which is quite similar but more focused on blending algorithm with business processes.

    And also there is BPMN to describe business processes and RACI matrix to describe roles.

    I know, it is not exactly what you asked for, but over 15 years of engineering work I find this tools the most useful. By the way, thank you for the post! I hope to find some inspiration from other comments too :)

  4. Comment on DuckDuckGo seems like a significantly worse search engine than Google despite SEO bloat, and I think community discussions mislead people by omitting that in ~tech

    I think you are right when you say that discussions of search engines often leave out some details. It seems to me that often such discussions come down to talking about general and non-specific use cases. For example, people mean queries like “what to cook with eggs,” “what movie was this actor in,” or “why do wombats poop in cubes?”

    Most people likely consider their usual profile of queries while discussing this topic. For instance, as a programmer, I evaluate search engines based on how easily I can find information related to computer science. For me, it turned out that the best search engine was Kagi.com, although it doesn’t know much about wombats. And during my university years I was an active user of Wolfram Alpha, but I wouldn't recommend it in general discussions now because it's too specific.

    Based on my experience using DDG, it is a fairly good search engine for general queries. It's probably not perfect, but it found what I needed. I absolutely couldn't find rare or specific information with it, but it was enough for me to find out, for example, the director's filmography. I still think it is a good option if you don't want the search engine to track your geolocation or search history.

    What topics do you usually search? How do you evaluate the quality of results?

    I'm a very huge fan of sandboxes and building, so my number one cozy game is Terraria. This game evolved very much through more than 10 years, and I think you could find any activity you like in it. There is huge aspect of building and exploration, small part of RPG, a bit of slasher and a lot of strategy if you want to fight bosses. So I switch to different goals in this game depending on my current mood.

    Another favourite game is RimWorld. It is also a sandbox game with huge focus on colony management and dynamic storytelling.

    From my point of view, if I use IDE to write code, the result does not belong to JetBrains or Microsoft. Same with AI assistents. I consider it as a tool that helps me to shape result code, but not to solve problems that need creative solutions.

    I'm curious, what if in a prompt text I'll ask AI to add license of it's choice, and the license will be free, could I use the result output as a part of program?
